HENRY STUEBNER, OF PHILADELPHIA, PENNSYLVANIA.

ANTIFRICTION-IBEARING.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed January 24, 1911. Serial No. 604,299.

To all whom it may concern:

Be it known that I, HENRY STUEBNER, a citizen of the United States,residing in the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania, have invented certain Improvements inAntifriclion-Bearings, of which the following is a specification.

My invention is an antifriction bearing comprising balls alternatingwith rollers having end races engaging the balls, and means for holdingthe balls and rollers in coiiperating relation.

It furthermore contemplates the use of a sectional outer bearing memberor journal box for inclosing the rollers and balls, the antifrictiondevices being adapted to be fixed relatively to the box sections, toprevent dissociation thereof upon the separation of the bearing, by themeans which hold the balls and rollers in the desired cooperatingrelation in the normal operation of the bearing.

The characteristic features of my invention are fully disclosed in thefollowing description and the accompanyingdrawings in illustrationthereof.

In the drawings, Figure l is a longitudinal sectional view and Fig. 2 isa part sectional end elevation of a bearing embodying my invention; Fig.3 is a longitudinal sectional view and Fig. i is a part sectional endelevation of a second form of bearing embodying my invention; Fig. 5 isa broken longitudinal sectional view and Fig. 6 is a broken endelevation representing a third form of bearing constructed in accordancewith my improvements; Fig. 7 is a longi-' tudinal section and Fig. 8 isa part sectional end elevation of a fourth form of bearing constructedin accordance with my improvements; Fig. 9 is a section taken on theline 9-9 of Fig. 8, and Fig. 10 is a perspective view illustrating boxand collar sections used in the construction shown in Figs. 7, 8, and 9.

The bearing, as illustrated in Figs. 1 and 2, comprises the journal box1 having the ends of its cylindrical interior surface 1' intersected bythe concave surfaces 1", the shaft collar or sleeve 2 having itscylindrical outer surface 2 intersected by the concave surfaces 2", thebearing rings 3 screwed on the ends of the collar, the balls 4 held bythe ring 3 in the races formed by the concave surfaces, and the rollers5, disposed between the box and collar, having their ends reduced toprovide the concave surfaces 5 which afford races for the balls, bywhich the rollers are spaced. This construction is well adapted forcarrying both a radial and an axial thrust.

As illustrated in Figs. 3 and d, thebox 11 has the ends of itscylindrical interior surface 11 intersected by the concave surfaces 11and the collar 12 has the ends of its cylindrical exterior surface 12intersected by the concave surfaces 12". Rings 13 are pro vided withspherical seats 13, and balls 14, engaged in these seats, are held bythe rings in engagement with the races 11 and 12". Rollers 16, disposedbetween the box and collar, have the concave end surfaces 16 providingraces for the balls alternating therewith, and rods 15, fixed to therings 13, extend through the rollers, which are journaled thereon.

In the form illustrated in Figs. 5 and 6, the box 21 has its cylindricalsurface 21' intersected by the concave surfaces 21", the collar 22 hasits cylindrical surface 22 intersected by the concave surfaces 22 andballs :23 are held in the concentric races formed by the surfaces 21 and22 by the engagement therewith of the split rings 2% and 25, which aresprung into the channels 21 of the box and the channels 22 of thecollar. Rollers 26 have the concave end surfaces 26 which afford racesfor engaging the balls, which alternate with the rollers, one beingspaced by the other. 7

In the form illustrated in Figs. 7 to 10 inclusive, the box is formed bysegments 30 and 31 having the respective interlocking longitudinal beads30 and grooves 31 to prevent lateral displacement and the respectiveinterlocking shoulders 30 and 31" to prevent longitudinal displacement.The collar is similarly formed of segments 32 and 33 having therespective interlocking longitudinal beads 32 and grooves 33 to preventlateral displacement, and the respective interlocking shoulders 32 and33" to prevent longitudinal displacement. Screws 34: and 35 hold therespective box and collar segments together. The box and collar areprovided with the respective races 36 and 37 for the balls 38 which areheld in position by the pressed metal rings 39 formed in sections; therings having the open seats 39 in which the balls engage and the flanges39 engaged by screws 40 carried by the box. Rollers d1, disposed betweenthe box and collar, have the concave end surfaces 41 providing racesengaged by adjacent balls. Rods 42 are fixed to the rings 39 and passthrough rollers 4:1, which are journaled thereon, and rods 43 are fixedto lugs 39 on the rings and pass through the balls 38, whereby the partsare connected together in the desired relation. ll ith thisconstruction, box sections having antifriction devices attached theretomay be conveniently placed on the median part of a shaft having endbearings and secured together with the screws 3a, or may be separatedand removed from the shaft without dissociation of the antifrictiondevices. By the engagement of the balls in the races formed by theconcave surfaces of the box and shaft, in which they are held by therings, the parts of the bearing are prevented from moving longitudinally relatively to each other.

Having described my invention, I claim:

1. An anti-friction bearing comprising an outer sectional bearing memberhaving therein an intersecting cylindrical surface and circular race,rollers having circular races registering with said race first named,balls movable in said circular races, sectional rings adapted forengaging the ends of said rollers, and means for connecting the sectionsof said rings with the sections of said member, whereby correspondingrollers are engaged to the respective sections of said member and areretained in connection therewith when said sections are separated.

2. An anti-friction bearing comprising an outer bearing member havinginterlocking sections, said member having therein an intersectingcylindrical surface and ball race, an inner bearing member havinginterlocking sections, said last named member having thereon anintersecting cylindrical surface and circular ball race, rollers betweensaid members engaging said cylindrical surfaces, said rollers havingball races registering with the races of said members, balls engagingsaid races, sectional rings, and means whereby the sections of saidrings are engaged to sections of one of the aforesaid members andremovable therewith, said ring sections being adapted for carrying saidrollers and balls withthe separated bearing sections.

3. An anti-friction bearing comprising an outer bearing member formed inseparable sections, a ring formed in separable sections, means forconnecting the sections of said ring with the sections of said member sothat the ring sections can be adjusted axially with relation to thebearing member sections, and alternating balls and rollers adapted to beengaged to the sections of said bearing member by said ring sections.

4. An antifriction mechanism comprising an outer bearing member having araceway groove therein, an inner bearing member having a raceway groovetherein concentric with said first named groove, rollers disposedbetween said bearing members and having raceway grooves therein, ballsdisposed in said grooves, and a ring for holding said balls in place.

5. An antifriction mechanism comprising an outer bearing member having araceway groove therein, rollers disposed within said member and havingraceway grooves therein, balls disposed between said rollers inengagement with the grooves therein and in said bearing member, andrings having seats for engaging said balls and holding them in position.

6. An antifriction mechanism comprising an inner and an outer bearingmember, a raceway groove in one of said members, rollers disposedbetween said members and having raceway grooves therein, balls disposedbetween said rollers and engaging the grooves therein and in saidbearing members, and a ring fixed to the other of said bearing membersand engaging said balls. 1

In witness whereof I have hereunto set my name this 19th day of January,A. D 1911, in the presence of the subscribing witnesses.
